This invention relates to winding machines and in particular' to thetraversing threadguide rail by which the yarn or thread is a, guided tothe spools or bobb-ins and made to traverse back and forth along thesame as the winding proceeds. The rail structure usually includes therail proper and a series of guides, usually porcelain, which are held inplace by wire spring members alternating with them, each two guidesbeing held by an intermediate spring member by having its extremitiesoverlapping them and seated in grooves in the two guides. Thisconstruction permits each guide to be slipped along one way or theother, as by tapping it, to adjust it in proper or centered relation tothe corresponding spool (it being recognized that if it is not socentered the windings will pile up against one head and form a channelnext to the other head of the spool) but it is faulty in that theadjustment cannot be effected to a nicety without great care and that inany event the reciprocating movement of the rail structure soon disturbsit, so that constant attention is required by some skilled person tokeep all the guides accurately positioned. Among other objects of thisinvention the principal on-e is to provide a thread-guide rail structurein which the guides are adjustable longitudinally and when once set oradjusted will remain so without further attention. In the example hereinset forth I retain the guides and springs sub-stantially as they haveheretofore usually been formed, but the threadguiding device includeswith the guide a plate or slide and the rail member includes the railproper and a base for the guiding device attached to the rail proper.

In the drawings, Fig. 1 is a front elevation of suiiicient of a windingmachine to illustrate the invention; Fig. 2 is a fragmentary frontelevation of the improved rail structure, with the rail proper partly insection;

plan of the guide, the slide and bobb-ins 3, and it has secured theretoon its top surface by screws 4 the elongated bent springs 5, each beingso secured at its midportion and having its ends reaching in oppositedirections lengthwise of and inclined toward the rail. So much is theusual construction. Each thread guide 6 has the usual form, being ablock (as of porcelain) with a top cross-cut notch 6a for the yarn andtwo longitudinal top notch-es 6b which receive said ends o-f the spring;its end surfaces converge upwardly.

A base member 7, consisting of an elongated plate having an upturned end7a, is seated on the rail proper and may have a pair of dependinglongitudinally alined and spaced tangs 7b which enter the groove la inthe top of the (wooden) rail l, being a little Wider than such groove sothat under pressure they bite or are pressed into its sides sufficientlyto obtain a hold against longitudinal displacement; the rail proper andthe base member may have marks or notches 8 to gage the proper positionof the latter opposite the spool.

On the base member is arranged the slide 9, consisting of an elongatedplate having the end 9a thereof corresponding to end 7a of member 7upturned. It also has two upstanding clips 9b, upwardly converged, andthese receive the guide in the manner shown, the plate of member 9 beingsomewhat elastic so that the clips act to clamp the guide, which mayhave a dowel 6c to enter a slot or recess 9c in the plate, which in turnmay have dowels 9d to enter a slot or recess 70 in the base.

The upturned ends 7a and 9a form lugs receiving a thumb-'screw l() whichis swivelled in one of them (as 9a) and tapped into the other.

Thus, while my thread-guide rail structure remains substantially asbefore so far as the guiding of the thread or yarn is concernedinparticular the ends of the springs serving to insure return of thethread or yarn to the guiding notch should it leave the same-adjustment,practically of micrometer character, is possible, and when once effectedremains permanent, mainly because a screw is used and also becausevibration or movement of the thread-guide device (here including parts 69) on the rail member (here including parts 1 5) is, independently ofthe screw, resisted by the spring, which is retained largely for thisreason. The spring, further, exerting pressure through said device andthe base holds the former against the latter and the latter against therail proper, the base being preferably held against Vany lateralmovement on the rail proper by the described engagement of its tangstherewith and said device against such movement by the screw and itsdowel connection with the base.

In these structures the thread frequently leaves the notch 6a of theguide and considerable winding thereupon proceeds without traverse,which of course produces a faulty package. The end portion of the spring5 being inclined downwardly toward the guide from al point remotetherefrom insures the automatic return of the thread to the groove inevery instance where it is unshipped from the groove, so that faultywinding from the cause indicated is not possible.

Having thus fully described my invention, what I claim is: r

l. A thread-guide device comprising a plate and a thread-guide, theplate having opposed clamping means integral therewith and projectingfrom one face thereof and eX- erting pressure on opposite upright facesof the thread guide, and said plate and threadguide having aninterengag-ed dowel and recess holding the thread guide against slippagetransversely of the line of clamping pressure and in a plane parallelwith that of the plate.

2. A thread-guide structure for a winding machine including a railmember, a threadguide. and a plate interposed between the thread-guideand said member and having on the face thereof adjoining the threadguidea pair of upstanding portions integral with the plate and offset fromeach other lengthwise of said structure and between which the threadguide is arranged and held, said member and plate having an interengageddowel and recess.

3. A thread-guide rail structure for a winding machine including arail-proper, a base seated on the rail-proper and adjustable along thesame, a thread-guide device carried by t-he base, said rail-proper andbase having a tongue-and-groove connection eX- tending lengthwise of therail-proper and nefiaee FREDERICK J.
